But not for the reason you would think. We were driving on the freeway, and I was happily chatting along to my husband about what a great flush I'd had, all the monster stones that came out, and then suddenly, I couldn't breathe. Just couldn't breathe. It was horrible. We flagged down a nearby ambulance, who gave my oxygen, and I was getting worse by the second. Couldn't walk, my hands and arms went stiff...uggg....transported me to the nearest hospital, where they shot me up with ativan and morphine, and then I got better. They said it was an anxiety attack. I'm so mad. never was in the ER before this month, and now it's twice from these gallstones. So how is an anxiety attack related to the flush, and what can I do to avoid it in the future? Thank you.
